Problem with active in links in dynamic WordPress nav menu.

I am working on this site: https://www.semblance.co.za/bronzeage/
All the pages are created as WordPress pages or template pages.
‘projects’ in the menu is the WordPress blog.

I have used the following code for the dynamic nav menu with the slug and links changed accordingly.

<?php if(is_page('contact')) { ?>
   <li class="page_item current_page_item"><a href="/contact/">contact</a></li>

  <?php } else { ?>
   <li class="page_item"><a href="/contact/">contact</a></li>
 <?php } ?>

It works fine for all the pages, except the ‘home page’ nav stay active with the page nav of the page that is being viewed.

I found the following code to use with the ‘projects’ (blog) page:

<?php if(is_home() && !is_paged()){ ?>
   <li class="current_page_item">
    <a href="<?php echo get_settings('latest-projects'); ?>" >projects</a>

   </li>
 <?php } else { ?>
  <li>
   <a href="<?php echo get_settings('latest-projects'); ?>" >projects</a>
  </li>
 <?php } ?>

It links through to the static ‘home page’.

Do anyone have some thoughts, ideas or solution/s for me?

Thank you in advance.
